SUBSOlL-PLOW AND ATTACHMENTS.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed August 22.1906. Serial N0. 331,672.

To all whom it may concern.-

Be it known that I, VVILLIAM M. HORNE, a citizen of the United States, residing at Trenton, in the county of Edgefield and State of South Carolina, have invented a new and useful Subsoil-Plow and Attachments, of which the following is a specification.

This invention has relation to subsoilplows and attachments for the same; and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide a subsoiler which is adapted to cut into the earth at depths varying from twelve to twenty-four inches below the surface thereof. YVhen used strictly as a subsoiler, the plow is not intended to move the earth, but simply to incise and open up crevices in the same for the purpose of accumulating moisture and ventilating clays or other formations lying beneath the surface soil. The plow is so constructed that attachments of special construction may be applied thereto, said attachments being adapted to throw the surface soil as the subsoil is being cut and opened.

In the accompanying drawings, Figure 1 is a perspective view of the plow. Fig. 2 is a horizontal section of the same, cut on the line 2 2 of 1. Fig. 3 is a perspective view of a wing attachment for the plow.- Fig. 4 isa perspective view of a modified form of bracket attachment for the plow.

The plow comprises a beam 1, to which is attached the standard 2. Said standard is provided in its forward edge with the notches 3, and to the forward edge of the said standard is attached the colter 4 by means of the bolts 5. The heads of the said bolts 5 are provided with cutting edges which are in alinement with the cutting edge 6 of the colter 4. The point 7 is attached to the front edge of the standard 2 at the lower end thereof. The forward end of the said point 7 is downwardly inclined, and the said point is provided with the cutting edge 8, which is in alinement with the cutting edge 6 of the bar4. At the lower end and rear edge of the standard 2 the recess 9 is provided, in which is secured the forward edge of the heel 10. Said heel 10 is provided with the rearwardly-extending portion 11. The parts thus described constitute the subsoil-plow; and the parts hereinafter described are various attachments that may be applied to the subsoilplow for the purpose of throwing the surface soil.

One form of attachment consists of a strip of metal bent to form upwardly and outwardly extending wings 12 12, with the intermediate portion 13, which is adapted to receive between its vertical parallel sides the standard 2, and the intermediate portion 14 rests within one of the recesses 3 of the standard 2, the said wings being held in place in the said recess by the colter 4,which is bolted to the front edge of the said standard. Surface-soil plows may be used in combination with the said wing attachments, one plow being used in, front of the wings and another plow in the rear thereof. The front plow may be of two forms. The bracket 15 is provided in its rear edge with a V-shaped groove 16, which receives the forward edge of the colter 4'. The plow 17 is attached to the plate 18, (see Fig. 4,) which in turn is attached to the forward edge of said bracket 15. The form of the bracket shown in Fig. 3 is provided at its forward edge with an elongated slot 19, to which a plow-point may be bolted and vertically disposed therein. The foot 20 may be bolted to the rear edge of the standard 2, said foot being provided at its rear end with an elongated slot 21, which is adapted to receive the bolt of a plow-point and may be adjusted along the said slot to adjust the vertical position of the said plow-point. From the foregoing description it is obvious that the lower portions of the plow operate for disturbing and breaking the subsoil, and

when the attachments are applied the surface soil may be thrown in various directions and spread by the said Wings.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A plow comprising a beam, a standard attached to the beam, a colter carried by said standard, a point located at the forward end of the standard, a heel located at the rear of the standard, wings carried by the standard, a foot attached to the rear edge of the standard, a shovel carried by said foot, a bracket attached to the colter and a shovel carried by said bracket.

2. A plow comprising a beam, a standard attached to the beam, a colter attached to the standard, a point attached to the standard, a detachable heel carried by the standard, adjustable Wings located bemy oWn I have hereto afliXed my signature in tween the standard and the colter, afoot attached to the rear edge of the standard, a l shovel adjustably attached to said foot,a 5 bracket attached to the colter and a shovel Witnesses:
